The value of the variable y is 9 given that BDJ=7y+2 and angle JDR=2y+7
From the attached diagram, we can see that the<u> sum of m<BDJ and m<JDR is complementary</u> (i.e. sums up to 90degrees)
Given the following
m<BDJ = 7y + 2
m<JDR = 2y + 7
Summing up to 90
m<BDJ + m<JDR = 90
7y + 2 + 2y + 7 = 90
7y+2y+2+7 = 90
9y + 9 = 90
9y = 90-9
9y = 81
y = 81/9
y = 9
Hence the value of the variable y is 9

X^3 -9x+1= 0 (minus 1)
X^3-9x=-1 (divide by 9)
x^3-x=-1/9
But it doesn’t work any further so you have written it wrong
Answer:
Yes, Always
Step-by-step explanation:
If M is the midpoint of line KL, then M, K, and L are collinear.
As you notice in the diagram, to be collinear means part of the same line.
